The potential advantages of the computational ghost imaging approach are two-fold. First, that single element detectors usually have better characteristics, e.g. for light an extended range of operating wavelengths, for electrons a larger quantum efficiency. Second, the flexibility of the illuminating patterns make them potentially more suitable for imaging optimisation by compressed sensing algorithms, reducing the number of required measurements [1]}, [2]}, [3]}. This ability to image with fewer measurements potentially increases the frame rate and/or reduces the exposure of potentially delicate samples to the illumination. Using these computational ghost imaging techniques, novel imaging systems have been developed that include imaging at terahertz wavelengths [4]}, time of flight imaging [5]}, [6]}, and imaging sensitive to fluorescent lifetime [7]}.
